Stain blocking paint holds back stubborn stains

We all know what it is like to paint stained walls and other surfaces – it is always a gamble if the paint will cover the stains and keep them from appearing ever again. Stain blocking paint is a coating specially designed to hold back even the most stubborn stains! It is usually a white or tinted basecoat or primer with extremely good covering properties.

Depending on the needs of the substrate you can choose for a stain block primer or basecoat which both make sure no stain will leach to the topcoat. Stains that are usually covered with stain block paint are those caused by for example nicotine, smoke, bitumen, crayon, grease and damp.
